CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is a continuation of, and claims the priority benefit of, U.S. Nonprovisional patent application Ser. No. 14/584,987, filed Dec. 29, 2014, now U.S. Pat. No. 9,621,575 issued on Apr. 11, 2017 and titled “Context Aware Threat Protection”. The disclosure of the above application is hereby incorporated by reference in its entirety, including all references cited therein.

TECHNICAL FIELD

This disclosure relates generally to data processing, and more specifically, to dynamic threat protection in a data network.

BACKGROUND

The approaches described in this section could be pursued but are not necessarily approaches that have previously been conceived or pursued. Therefore, unless otherwise indicated, it should not be assumed that any of the approaches described in this section qualify as prior art merely by virtue of their inclusion in this section.

Within a modern threat protection system, a policy can be defined using Internet Protocol (IP) addresses to identify nodes to protect or block, or nodes against which a further policy can be executed. In general, the basis for the protection policy is defined statically by a user and then manually applied. The challenge, however, is that because service providing systems are dynamic with the state of services, clients, and servers in constant flux and, therefore, static policies can only be effective for a short period of time. Events within a service providing system can constantly change the state of the service providing system. User authentication, changes in reputation, mobile device roaming, and IP address lease expiration are all examples of events which negate the usefulness of a static policy.

As static policies lose their relevance, threat protection systems attempt to automatically ascertain the correct policy through active challenges and passive observation of flows. However, selecting the correct policy is a resource-intensive process that amounts to marginally effective “guess work” by the threat protection systems.

SUMMARY

DETAILED DESCRIPTION

The following detailed description includes references to the accompanying drawings, which form a part of the detailed description. The drawings show illustrations in accordance with example embodiments. These example embodiments, which are also referred to herein as “examples,” are described in enough detail to enable those skilled in the art to practice the present subject matter. The embodiments can be combined, other embodiments can be utilized, or structural, logical, and electrical changes can be made without departing from the scope of what is claimed. The following detailed description is therefore not to be taken in a limiting sense, and the scope is defined by the appended claims and their equivalents. In this document, the terms “a” and “an” are used, as is common in patent documents, to include one or more than one. In this document, the term “or” is used to refer to a nonexclusive “or,” such that “A or B” includes “A but not B,” “B but not A,” and “A and B,” unless otherwise indicated.

The techniques of the embodiments disclosed herein can be implemented using a variety of technologies. For example, the methods described herein may be implemented in software executing on a computer system or in hardware utilizing either a combination of microprocessors or other specially designed application-specific integrated circuits (ASICs), programmable logic devices, or various combinations thereof. In particular, the methods described herein may be implemented by a series of computer-executable instructions residing on a storage medium such as a disk drive, or computer-readable medium. It should be noted that methods disclosed herein can be implemented by a computer (e.g., a desktop computer, a tablet computer, a laptop computer, and a server), a game console, a handheld gaming device, a cellular phone, a smart phone, a smart television system, and so forth.

The present disclosure relates to methods and systems for dynamic threat protection. According to an example method, a client can send a service request to a server in a data network. The service request may include one or more data packets. The client may be associated with a data source operable to collect real-time contextual data associated with the client. In particular, the data source may include a hardware node or a software node in the data network and may be in communication with the client. The data source may be operable to provide the real-time contextual data associated with the client to a dynamic threat protection system.

The dynamic threat protection system may be operable to select and apply a security policy with regard to a specific client. To this effect, the dynamic threat protection system may have a real-time understanding of the client-specific contextual data received from the data sources. The dynamic threat protection system may receive the service request from the client. Upon receiving the service request, the dynamic threat protection system may retrieve the real-time contextual data of the client from the data source associated with the client. Alternatively, the real-time contextual data may be retrieved from the service request received from the client. The real-time contextual data may include authenticated user data, IP address renewal, wireless roaming information, network path, updated payment information, age of an account, and the like.

Based on the real-time contextual data, the dynamic threat protection system may assign a security threat score to the client. The assigned security threat score may be used by the dynamic threat protection system to select and apply a specific security policy to the client. More specifically, by receiving the real-time contextual data, the dynamic threat protection system may update “on the fly” the security policy with respect to a specific client. Additionally, a common event bus may be created to group many disparate data sources associated with the clients to allow the dynamic threat protection system to apply the most relevant update to any particular security policy.

Referring now to the drawings, FIG. 1 shows an environment 100 within which methods for dynamic threat protection can be practiced. The environment 100 may include a network 110, a client 120, a client device 130 associated with the client 120, a data source 140, a server 150, a dynamic threat protection system 200, and a third-party contextual data providing system 160. The data source 140 may be associated with the client 120 and may include a network resource, such as a network node, that collects real-time contextual data 180 associated with the client 120. The client 120 may perform a data service session with the server 150 by sending a service request including data packets 170 from the client device 130 to the server 150. The dynamic threat protection system 200 may receive the real-time contextual data 180 from the data source 140. Based on analysis of the received real-time contextual data 180, the dynamic threat protection system 200 may select a security policy 190 to be assigned to the client 120. The server 150 may process the data packets 170 of the client 120 based on the security policy 190. Alternatively, the dynamic threat protection system 200 may receive the real-time contextual data 180 associated with the client 120 from the third-party contextual data providing system 160.

The additional security measures may include analyzing contents of the data packets associated with the client for adherence to a predetermined standard.

FIG. 6 is a block diagram 600 illustrating applying policy to subscribers in a service providing system. The service providing system (not shown), such as, for example, a game providing system, may have a number of subscribers, shown as subscriber 605 and subscriber 610. The subscriber 605 and subscriber 610 may be requested to provide subscriber-specific information, such as subscriber payment data 615. The service providing system may collect and store the subscriber-specific information in a subscriber list 620. The subscriber list 620 may contain data related to authenticated subscribers, i.e. subscribers registered in the service providing system, and subscriber-specific information. The subscriber-specific information may further include operating system data, patch level data, the latest virus scan data, up time data, and so forth. In case the subscriber 610 does not enter the subscriber payment data, an indication 625 that no payment data is available for the subscriber 610 may be stored in the subscriber list 620.

The dynamic threat protection system 200 may be provided with the subscriber list 620 containing an updated list of authenticated subscribers 605, 610 with updated subscriber-specific information. Based on the provided subscriber-specific information, such as subscriber payment data 615 or indication 625 that no payment data is available for the subscriber 610, the dynamic threat protection system 200 may provide the subscriber 605 with preferential quality of service over the subscriber 610. For example, the subscriber 605 with valid payment data may be provided with a full access policy 630, while the subscriber 610 with no payment data may be provided with a restricted access policy 635. Therefore, using the subscriber-specific information, the dynamic threat protection system 200 may apply the security policy of extreme relevance to a specific subscriber.

FIG. 7 is a flow diagram 700 illustrating providing a service in response to a service request, according to an example embodiment. The dynamic threat protection system may receive a service request from a client at block 710. At block 720, the dynamic threat protection system may retrieve real-time contextual data associated with the client from the service request or from a data source associated with the client. The real-time contextual data is illustrated in detail with respect to FIG. 5. Upon retrieval of the real-time contextual data, the dynamic threat protection system may determine whether the client is trusted at block 730. The determination may be performed based on the analysis of the real-time contextual data to determine the security threat score of the client. In case the security threat score assigned to the client is above a predetermined threshold threat score, the client may be determined to be trusted. At block 740, a first type of service, e.g. unlimited service, may be provided to the trusted client. In case the security threat score assigned to the client is below a predetermined threshold threat score, the client may be determined to be untrusted. At block 750, a second type of service, e.g. limited service, may be provided to the untrusted client.
